I may have made a slight mistake in the steps I gave you to do the JMP Chi-Square question in Assignment 4.  If you notice that the table JMP ends up making has the columns and rows inverted compared to the table given in the question, simply change the column you called Y and the column you called X in the Fit Y By X pop-up menu.  Note that you get all the same scores regardless, this is just a stylistic thing.
